Hi @Andrew,
My set-up is as you describe but I am failing to get the paste function to work and use CMD V presently.
I guess there must be a bug somewhere, so I will wait patiently for the next version of Mojave beta to be released and see if that solves the issue.

Hi @Shraden
You are correct and I know that there are discussions between Alfred and 1Password underway.
This thread on Agilebits forum that I have contributed to should assist - note the last few posts.
